Infocom Cabinet: Sorcerer.
A collection of digitized scans from a large cache of documents related to the game publisher Infocom, Inc. of Cambridge, MA. Assembled by Steven Meretzky of Infocom.
During his time at Infocom, Steve Meretzky meticulously gathered thousands of pages of notes, journals, maps, memos, forms and other printable materials related to all aspects of Infocom, and kept them in his basement for decades. During the GET LAMP production, Jason Scott scanned in roughly 9,000 pages of these documents across a number of months, borrowing the materials from Steve and scanning them as quickly as possible, at around 600dpi. From these scans, a portion was used in the GET LAMP movie to illustrate various scenes and descriptions by interviewees.
From the Wikipedia description
Sorcerer is an interactive fiction computer game written by Steve Meretzky and released by Infocom in 1984. It is the second game in the magic-themed "Enchanter trilogy", preceded by Enchanter and followed by Spellbreaker. It is Infocom's eleventh game.
Following the unlikely defeat of Krill in Enchanter, the player's character has progressed from an Apprentice Enchanter to earning a coveted seat in the Circle of Enchanters. Belboz the Necromancer, the leader of the Circle, has become not only a mentor but a close friend as well. Lately, though, Belboz has seemed different. He's always distracted, even talking to himself at length. Whatever he's dealing with, Belboz doesn't see fit to confide in anyone. Surely he knows what he's doing.
But then, Belboz suddenly disappears. If he is under the influence of some evil power, the results could be disastrous — Belboz is one of the most powerful Enchanters in the land. Someone must uncover what has happened to him, and naturally that task falls to the player's character.
